Fingerprint Reader (Biometric) on Android! Really Worth It?

The smartphone has become an essential item for most people now. Since cheaper Android phones to high-end iPhones, the options are increasingly diverse and sophisticated.

The evolution of smartphones led to devices that simply received and made calls to become warehouses for a lot of personal information, and even financial information. People use virtual portfolios to recharge your mobile phone, balances or use your cell phone as a credit or debit card when making purchases. But how do you keep this information secure? How about a fingerprint reader?

Fingerprint Reader for Android and iPhone

Passwords, PIN codes, standards, and other types of codes are used to a certain degree of safety in the use of smartphones. They are a single layer of security, simple, that can be overcome with a little bit of guesswork, or a bit of social engineering.

Fingerprint sensors appear to give an extra layer of security for devices. The use of fingerprint detection technology took off on mobile phones because it allows a convenient and reliable security of our data on your smartphone.

The fingerprint reader to smartphones and tablets is an extra layer of security. Its usefulness, however, is still somewhat limited, while applications are adopting the technology.

Fingerprint Reader on Your Phone Worth?

When a phone with support for fingerprint sensor is connected, he initially prompts the user to enter the data for your phone. The sensors track the prints and store on the phone. A reader connected to the smartphone does the same thing.

The problems are that the fingerprint readers are used by very few applications. And are not as safe as they seem. Authorization processes by reading the fingerprints, for example, still leave room for hackers to use vulnerabilities in the process. It’s very easy to also copy the thumbprint of a person, using relatively simple methods. Add to that the fact that few applications use the fingerprint reader, and we have a bit of a white elephant, which is expensive.

Mobile Phone with Fingerprint Reader: There’s Still A Bit to Be A Good Buy

We can assume that our fingerprints are not really safe. But if that is the case, then they are not really worse than passwords? After all, we are warned several times to change our passwords and PIN codes regularly, and never use the same password for multiple devices or accounts. In the case of a fingerprint sensor, there’s much less that you can do to ensure variability. Once the fingerprint data is stored, your security is compromised on all devices at all times.

Apple and Google can bring more resources to increase security, but the possibility of violating the security still remains. The prints are not really a good solution. The same fingerprints will unlock your phone and your office computer, and any other point where biometrics is used.

The average cost of a digital reader is a 1/4 of the minimum wage. Digital readers embedded in cell phones are only available in high-end appliances or intermediaries, which cost between 1.5 times the minimum wage to more than 4 times the minimum wage. As the security of biometric reader is not very advantageous for a strong password, the reader should only be purchased by those who really need it.

For example, companies where the point is done by reading biometrics, medical offices where the reader is used to authorize consultations by health insurance, banks and financial institutions that use this medium.

The news is interesting. It’s just too expensive and not worth. Soon, new features, such as the use of password, and even heart reading selfies in conjunction with digital printing, can become the most reliable biometric security. But we still have a few years before that moment.
